    Maverick upgrade has left screen flashing
    Last night I updated Mavericks, now the iMacs home screen flashes and there is no app bar........
    Anyone have any ideas?

    All I can find online is something about Google and it not working with Mavericks, but I'm struggling to locate it.....


    So much editing to do..........

    G'day and welcome to the forums.

    Try as nickry suggests. Do you mean no Dock? What was thebupdate ~ OS X.9.3 to 9.4 or what?

    Which model iMac and is it covered by warranty and/or three year AppleCare?
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
